I've always liked working on things like Aaon and Lennox L Series package units, but I've now encountered something that makes me question the whole concept of having the compressors on a shelf in the same compartment with all of the microprocessor and electromechanical controls.
This doesn't look good.
Nope, not good at all.
First time I've ever seen all 3 terminals blow out!
This is going to take many cans of electrical and electronic parts cleaner...
I'm thinking there is a connection to this issue.
I didn't get out a measuring tape, but my eyeball tells me this is more than the 1" of belt deflection called for by the sticker on the end of the blower housing.
As far as anyone knows, this is the original factory belt, on a 6 year old unit with a high speed high static pressure reverse bias blower.
I'm thinking the belt should be replaced every year...
